Hi
I tried to post couple of times earlier and somehow it is not showing up and also no notification has been received for approval/rejection. SO, trying to re-post again . Apologies for creating duplicate items ( if any )
We know that as a part of NW 7.4 SP00/SP02 , a new check in code inspector has been introduced which will all the select queries with for all entries addition and having the possibilities of replacing them with join etc. We are trying to check whether performance of FAE will degrade if do not change anything after upgrading to ECC on HANA. We do not want to optimize for now and we are ok if all the for all entries are giving the same performance result before and after HANA migration. We have found that oss note 1662726 which says "
The performance of a select statement with a FOR ALL ENTRIES (FAE) clause
is poor."
please make a note that we do not want to improve the performance but we want to evaluate whether FAE gives same performance in both hana and non-hana DB if all the other settings (e.g., as per note 48230 ) remain same.
Any advice will be appreciated
Regards
Gairik
